TO ALL WHOM IT MAY CONGERN:

Beit known that I, DAVID MARSHALL, of the city of Pittsburg, in the county of Allegheny, and State of Pennsylvania, have invented'a new and useful Improvement in the Socket-Board of Reed Instruments; and I do hereby declare the following to be a full, clear, and exact description-thereof, reference being had to the accompanying drawing, making a part of 'this specificatiomgin which- Figure 1 is a sectional view Aof my improved socket-board. p v

Figure 2, by a bottom view, illustrates my mode lof makingitlie same; and

Figure 3, by a sectional view, illustrates my improvement in a. modified form.

Iiikeletters of reference indicate like parts in'each.v p

My improvement relates-to the censtructionot` the socket-board, and consists in fac'irig the ordinarysocketboard with another slotted or socketed board, the sockets in the latter, or facing-board, being shortenthan those in the former, or main board, so that the -two being fitted together, the' main socketswill be covered at their extremities, and between their ends will be left open for the passage of air. l

To enable others skilled inthe art to make and useA my invention, I will proceed to describe its construction and mode of operation.

In the manufacture of reed-instruments, the wind-chest is covered by the socket-board b, in which is cut n. series of loing, narrow slots or sockets, a. These sockets arc covered by the'reed-board d, except that in the under side of the reed-board cl, and immediately over one or both extremities of each socket a, reed-cells c are cut, into which are fitted the reeds e. The air then being forced by bellows through the reeds e, produces the musical vibrations. l l

Inmy improvement, I face the main socket-board b, on its under side, or on the side next the wind-chest, with another slotted or socketed boar-(1,1', in which are cnt slots v.or sockets s, corresponding in number and arrangement to the sockets a in the board b. -These sockets s are shorter than the sockets a, so that when the two boards are glued togcther,as shown in the drawings, the board will over the ends of the sockets a immediately under the reed-cells c, and leave a long opening along the sockets s, and the middle of theA sockets a, for the passage-of air; but I sometimes close up the middle part of the sockets s, by inserting a strip, as at o, iig. 2, leaving short slots or sockets s for the passage ofair; or such short sockets 8 may be cut directly inl the board i', The boards z' and b are glued firmly together, so as to give atight joint and vibrate in unison.

Both sockets may, however be cut in the same board, or a single socket, u, fig.. 3, with inclined ends, may be used with profitable result, the ends being so inclined that'A the air passing through the reeds shall strike against the inclined faces u u. 1

The advantage of this mode of construction is that the currentsot` air passing through the reeds e irnpinge' againstithe facing-socket board i, or against the inclined facesu, and cause it and the board b, or th'e hoard b', to vibrate-in unison therewith, thus giving to the latter somewhat of the character ot' a sounding-board, Also, the air, after leaving the reeds c, has to take a somewhat circuitous route to reach the wind-chest, in consequence of which the musical tone produced'is assimilated to that of the pipe-organ. In this way I make musical reed-instruments of a purer and greatly improved quality and strength of tone.

What I claim as my invention, and desire to-seeurc by Letters Patent, is-

The board z', placed immediately belowand in contact with the soeket-board b, and 'having an opening or openings, s s', under each reed, coinciding with but shorter than the openings 4or sockets a in the socket-board, substantially as and for the purpose described. i

In testimony whereof, I, the said DAVID MARSHALL, have hereunto'set my hand.
